The ACL2 Workshop Series
We hold regular workshops. In 2010, the ACL2 Workshop did a one-time
merger with TPHOLs to form the first International Conference on
Interactive Theorem Proving (ITP). Such a merger may occur again, but
whether or not that happens, the ACL2 community is encouraged to
participate in ITP. Other conferences of particular interest to the
ACL2 community include CAV (Computer Aided Verification)
(Formal Methods in Computer Aided Design).

Jared Davis and Keshav Kini have graciously supplied a listing of
bibtex entries for the ACL2 workshops through 2017 (would be nice
if extended past 2017; any volunteers?).
ACL2 input files (certifiable books) from the preceding workshops are
available in the ACL2+Books GitHub
repository, specifically, in
for workshop contributions.
ACL2 Seminar at UT
An ACL2 seminar has met regularly at the University of Texas. A list of past
talks, generally accompanied by abstracts and sometimes slides, may be found on
